First show that aired after William Talman's dismissal on morals charges. The opening scene now shows Perry holding a file, and the camera freezes. The names of the other costars (minus Talman) are then listed.
The Matisse painting whose authenticity is at the center of this storyline is said to have cost $200,000. In recent years, original Matisse artworks have sold at auction for prices ranging from $33 million to more than $80 million.
(At about 13:30) As in many other episodes of the show, the address on the registration of David Lambert's car is "1040 N. Las Palmas Ave." - the address of the studio where numerous episodes of the series were filmed.
Per various car registrations in the series, the same license plate number (NFL 252) has been seen, or will be seen, five times for five different characters. The episodes are The Case of the Bartered Bikini (1959), The Case of the Prudent Prosecutor (1960), The Case of the Mythical Monkeys (1960), this one (The Case of the Crying Cherub (1960)), and The Case of the Barefaced Witness (1961).
Even though Carmen Phillips' character's first name is spelled "Liza" (with a "z") in the closing credits, in the show itself there are two separate notes that spell the first name as "Lisa" (with an "s").
